PIN-FASTENER.

Specification of Letters Patent.

Patented Oct. 5, 19.20.

Application filed November 22, 1919. Serial No. 339,817.

T 0 allwhom it may concern:

Be it known that I, MARY STARMER, a citizen of the United States of America, residing at Newport News, in the county of IVarwick and State of Virginia, have invented new and useful Improvements in Pin- Fasteners, of which the following is a speciiication.

The invention relates to an improvec. oin fastener adapted for use either as a safety pin, or: as a curtain hanger, and is also applicable for use in connection with brooches, buckles, buttons, &c. being designed particu larly with a view to holding the front piece or bar of the fastener flat against the article pinned, and secured so that the device can not tilt or sag downwardly. To this end the invention consists essentially in combining and arranging the front bar and spring bar or spring pin in the same horizontal plane, with the head of the pin and its spring coil or base in a vertical plane and at right angles to the plane in which the front bar and spring base lie, and the invention further consists in certain details of construction in the fastener as a whole whereby an efficient and convenient fastening device is attained.

In the accompanying drawings, two complete examples of the physical embodiment of the invention are illustrated, one in the form of a safety pin and the other in the form of a curtain hanger with a hook formed integrally therewith, these being the best'modes I have so far devised for the practical application of the principles of the invention, but it will be understood that other forms of fasteners are contemplated and that the subject matter of the invention may readily be incorporated in modifications of these constructions.

Figures 1 through 5 show the embodiment in a safety pin and Figs. 6 through 9 illustrate the invention embodied in a curtain hanger.

Fig. 1 is a front elevation of the safety pin.

Fig. 2 is a back View of the safety pin.

Fig. 3 is a top plan view of the safety pin as illustrated in Fig. 2.

Fig. 4 is a sectional plan view on line 4-4.- of Fig. 1.

Fig. 5 is a transverse vertical sectional View on line 5-5 Fig. 2.

Fig. 6 is a front view of the curtain hanger.

Fig. 7 is a top plan View of the fastener of Fig. 6.

Fig. 8 is a vertical sectional view at line 88 of Fig. 6.

Fig. 9 is a vertical sectional view at line 9-9 of Fig. 6.

In the preferred form of the invention as embodied in Figs. 1 through 5, the fastener is made up of a single piece of wire suitable for the purpose and manipulated by proper machinery to fashion the complete fastener, the front bar 1 being curled partly around to form at one end the head 2, which head may be round, oval or other desired shape, and is preferably capped with a metal plate 3 having its edges 4 turned over the head to securely hold the cap on the head with its smooth face to the front. At the back or rear, the cap is fashioned with a downwardly bent fiat hook 5, lying as compactly as possible and parallel with the cap, and at its lower end, approximately the center of the cap, the hook flanged or turned inwardly and upwardly to form a seat or recess 6 for the point of the pin 7 to rest in. In this manner the head provides a receptacle or pocket for the point of the pin, within the cap 3 and the pin is concealed and its point covered to prevent catching in material, or from being unfastened accidentally.

The front bar and the pin, it will be noted, lie in the same horizontal plane with the head at right angles thereto, and at the opposite end of the fastener the pin and bar merge into the base coil 8,'which is shown as substantially circular and at its outer end is formed with an inwardly bent portion forming a notch or recess 9 alined in the same plane with the pin and bar, to receive the bent end 10 of the pin 7 which thus extends around to the front from the rear and the wire is projected, horizontally, across the base or coil ring 8 to form a flat brace 11 in line with the bar 1. At 12 in Fig. 4: it will be seen that the portion 18 of the pin, contacts with the flat brace 11 as a support for the spring when it is fastened with its point in the head or its pocket 6, and the seating of the bend lO in its notch 9 provides a stable base or support for the resilient or spring pin 7 The safety pin is utilized in a multiplicity of ways and it will be noted that the head and the base coil stand in planes perpenbar.

dicular to the parallel, horizontal pin and bar, the pin being separated from the bar a flat, unobtrusive, fastening device which.

braces itself and is thereby prevented from sagging or tilting when in use. When the material, through which the pin is passed, is thin, the material may slide in between the pin and brace bar at 12, and thicker ma terial will be incased between the front bar and pin the latter curving because of its resiliency, to allow for the thickness of material, and when the pin point iscaught under the hook and in its pocket or shield the bulk of the material is retained between the pin and frontbar. V

In the curtain hanger in Figs. 6 through 9, the front bar 1 is fastened with a book 14, and the cap of the safety pin is dispensed with and the head is formed by the loop 2 the end of the wire being coiled at 15 about the bar 1, and a notch 16, similar to the notch 9 in Fig. 1 being provided for the pin 7 to catch in when pin is fastened. In other respects the curtain hanger or pin-hook is similar to the pinfastener above described, and in both forms of the invention the front bar and pin are in the same horizontal plane while the head and base or spring coils lie in a vertical plane at right angles to that of the pin and In both forms of the invention the single wire is bent and fashioned to provide a flat and smooth, compactly arranged fastening device which is neat in appearance and has no projections that would be likely to catch into or tear delicate materials.

What I claim is 1. A fastening device comprising a front bar and pin retaining'head, a circular base at the other end of the bar fashioned with a diametrically disposed brace bar alined with the front bar, said brace bar extending around and back of the circular base and a pin member extending back of the bars and in the same horizontal plane therewith.

2. A fastening device comprising a front bar and pin retaining head, a base coil at the other end of the bar provided with an end notch and an integral brace bar alined with the front bar and extending around the notched coil, a pin member'extending back of the bars. and adapted to contact with the brace bar, said bars and pin being located in the same horizontal plane, and the head and ,coil located'in'the same vertical plane, as described.

V 3. A fastening device comprising a front bar a spring pin and a pin retaining head, said head fashioned as a loop, a cap plate having a flangeturned down over the wire of the loop, an integral upturned hook on the cap flange, and an inwardly and upturned seat fashioned at the end of the hook for the pin point.

4. The combination in a pin fastener with the front bar, pin and pin retaining head, of a base coil at the end'of the bar opposite the head and disposed in the same vertical plane, an integral diametrical brace bar extending across the coil and alined with the front bar, said bars and pin located in the same plane and in a plane at right angles to the head and coil.

5. A fastening device comprising a front bar and a pin retaining head fashioned as a loop, a cap plate on the loop formed with a downwardly extending flange and an upturned hook forming a seat for the pin point, arbase coil at the opposite end of the front bar provided with an end notch alined with the bar, an integral brace bar alined with the front bar, extending across the' coil and extending around'the notched coil, and a pin member extending back of the brace bar and adapted to bear against said brace bar, said bars andpin located in the same plane. and said head and coil located in a plane at right angles thereto.
